That other thread is cool but it's kinda bogged down. Here are some tools and tips I have used for the past coupla years that work flawless.

Outpost Firewall Pro

Belarc Advisor(Very detailed info about your computer , it's vulnerablities, updates you may or may not have and a whole lotta other shit.

Index.dat suite(Use this to see some interesting stuff if you thought you covered your tracks. there are files on your pc called index.dat. there is an index.dat file for many of the features on your pc, email , web browser , windows media player.
you cant open them, you cant delete them, shit...you cant even find them ....this can do all of that. This one's a trip A MUST HAVE.

Eraser(WIPE EVERY THING ...FOR GOOD. Aside from physically destroying your hard drive, this is the best for wiping free space.

BE CAREFUL WITH THIS ONE
If for some strange reason you want to quickly destroy the contents of your entire drive use this. PUT IT ON A FLOPPY OR CD ROM AND CLEARLY LABEL IT. YOU HAVE BEEN WARNED. Go to your bios settings and set your shit to boot from the A or CD rom drive with the nuke on it. That's it. But if you have the time. I suggest physically taking it apart. If you do take it apart you'll get some sick ass magnets from it.

TIPS:
If you use XP disable the built in firewall. Use the one above. The XP firewall is pretty useless.
Go to Administrative tools/Services and disable Messenger. you don't need it(the majority of you won't, and it has nothing to do with instant messaging.) Disable any service that allows remote administration of your pc , desktop or registry.
All this has worked 100% for me over the past couple of years.
